ROTARY FOLDING MECHANISM.

Application filed September 14, 1910. Serial No. 582,101.

To all whom it may concern:

Be it known that I, HENRY F. BEGHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in R0:

tary Folding Mechanism; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in rotary sheetfolding devices especially adapted for use .in folding newspapers printed on rotary web presses; and the object is to profolder which can operate efficiently at very high speed.

The principal object of the present invention is to provide means for adjusting the folding blades simultaneously and to enable this object to be accomplished at one operation by one adjustment of parts so that the blades can be adjusted quickly and accurately and with great nicety by the ordinary pressman without'requiring any particular or unusual skill in so doing.

1 will now explain the invention in detail with reference to the embodiment thereof illustrated in the accompanying drawings which show one practical form of the invention and the description of which will enable any one familiar with the art to clearly understand theinvention and adapt it for use in various styles of folders employing rotary cutting and folding devices.

In the drawings-Figure 1 is an end elevation of a rotary folding apparatus equipped with my invention. Fig. 2 is a side elevation thereof with the cutting cylinder and the stacker omitted. Fig. 3 is a sectional view on line 3-3, Fig.2. .Fig. 4 is an enlarged-detail section ofthe bearings of shaft 5. Fig. 5 is an enlargeddetail section of the devices for fastening plate 4.

In the drawings 1 designates the male cutting cylinder and 2 thefemale cutting and folding cylindef which may be mounted as usual on shaft 1, 2 journaled in bearings on asuitable frame and provided with the usual cutting devices l 2. The cylinder 2 is also provided with the usual pinoperating devices as indicated at 2 in the drawings; and within this cylinder at diametrically opposite points are two rotary tucking blades 3 which are .mounted upon Specification of Letters Patent.

the shaft 2* as usual.

' the cylinders 1 and shafts 3 journaled in bearings 4 attached Patented Oct. 31, 1916.

to rocking plates 4 rotatably mounted upon the shaft 2*, three of such plates being preferably used. The outermost plates 4 are provided with segmental racks 4 on one side, which racks mesh with pinions or teeth 5 on a shaft 5 journaled on the heads of cylinder 2. Shaft 5 projects at one end beyond the adjacent head of the cylinder and issquared as shown at 5*, so that a. wrench can be applied to this end 5*,- and by turning it the disks 4 can be rotatorially shifted on shaft 2 so as to adjust the tucker blade shafts 3 laterally forward or back as may be desired. 15

One or both of the end disks 4 may be provided with are shaped slots 4 through which pass bolts 4 which are tapped into openingsin the adjacent head of the cylinder, see Fig. 5, and the plates may be locked against rotation by tightening bolts 4 thereby locking the plates 4 and the tucker blades in their adjusted position.- When the tucking bladeshafts are to be adjusted the bolts 4 are loosened and plates .4 are then shifted, by turning shaft 5 as described, to the desired position and then bolts '4 are tightened so as to lock the plates 4 to the cylinder heads and thereby secure the tucker blades 3 in their adjusted position.

The blades 3 are rotated on their own axes as thecylinder 2 revolves, by means of pinions 3 on one end of each shaft 3 meshing with an internal gear 6 attached to the box in which shaft 2 rotates and surrounding arrangement and construction both tucker blades 3 can be adjusted at one movement; and as a considerable rotary movement of shaft 5 willimpart but a slight rotary move- I ment to the plate 4, it is possible to adjust the tucker blades simultaneously in the cylinder with the greatest nicety. v

The novel means for adjusting the folding blades can be applied to different forms of rotary folders and I do not wish to limit myself to the particular construction thereof herein shown.

With the described I have conventionally indicated in the drawings other parts of web folding apparatus usually employed in connection with 2,v the part marked 7, Figs. 1 and 3., representing part of the cowcatcher former at the apex of which arethe first fold rolls 7, 7, from which the papers pass on-betw'een the cylinders land 2 being 4o I folding cylinder beside the severed by the blade 1 fold rolls 8, 8*

justing the nuts 8 cally opposite at the proper time, and carrled on by the pins past the second between which the folded papers are tucked by the rotary blades 3 in the usual manner; and then they 'are drbpped in front of the stacker 9. The roll 8 is preferably journaled in arms 8 attached to a rock shaft 8 having crank arms 8 to which are connected bolts 8 transfix- 'ng rocking eyes 8 attached to the frame,

"springs 8 being interposed betweenthe arms 8 and the eyes 8 to hold. the roll 8 yieldingly against or toward the roll 8. By ad- 8 the roll 8 may be held at any desired distance from the roll 8, to prevent re-print or offset on papers passing between the said rolls, and'to accommodate varying numbers of pages passing between the rolls. This device will also permit the passage of small irregularities whichmight jam and cause a clog between fixed rolls.

What I claim is:

1. In a folder, the combination of a folding cylinder, adjustable plates associated with the cylinder provided with diametribearings for tucker blade shafts, tucker blade shafts journaled in said bearings, a rotatable shaft in the cylinder beside said plates,

shaft and said plates foradju 'sting the latter rotatorially, and means for locking the plates when adjusted. 2. In rotary folding apparatus, the combination of cutting and folding cylinders,

adjustable plates associated with the folding cylind r, tucker blade shafts journaledin said ates, tucker blades attached 'to said shafts, blade shafts; with a shaftlmounted in said plates and gear ing between the said shaft and plates for slots adjusting the latter. a 1 3.
